Time of Flight Diffraction | TOFD

TOFD is a highly accurate and reliable method for assessing the integrity of welds, providing critical information about the material composition and stability of structures.

This non-destructive testing method is widely used to examine welds in industries such as petrochemical, chemical, oil and gas, power generation, and fabrication.

At Reliance Inspection, we are committed to providing our clients with the highest quality NDT testing services, and our TOFD inspection services are no exception.
